HYDRANT-CAP.

Specification of Letters Patent.

Patented Sept. 19, 1916.

Application filed May 7, 1913. Serial Nb. 766,183.

To all whom it may concern:

Be it known that we, JAMES E. REID and EDWARD J. SCHOGK, citizens of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Hydrant-Caps; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends improvements in hydrant caps and relates more particularly to a cap having means for preventing the same corroding where it engages the hydrant body.

The common types ofhydrant caps now in use are usually formed of cast iron and when screwed tightly upon the nipple of a hydrant come in contact with that portion of the hydrant which surrounds the nipple and tend to corrode thereto. Hydrant nipples are usually made of brass and therefore it is only around the face of the cap which engages the hydrant proper that the corrosive action takes place. The interior of the cap which is threaded upon the nipple does not tend to corrode fast thereto because, as before stated, hydrant nipples are usually formed of brass.

Our invention aims to provide a hydrant cap having a facing ring preferably formed of brass but which may be formed of any suitable metal which corrodes less rapidly than cast iron of which latter material the hydrant bodies are usually made.

With these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

For a complete understanding of our invention, reference is to be had to the following description and accompanying drawings, in which,

Figure 1 is a sectional view through our improved cap, parts thereof being shown in elevation, Fig. 2 is an end view of the cap with the facing ring partly broken away, and, Fig. 3 is a fragmentary detail view in elevation, of the ring looking at the inner face thereof.

Referring in detail to the drawing by numerals, 5 designates, generally, a hydrant cap having a hollow cylindrical shaped body 6 which is open at its inner end and closed at its outer end by the wall 7. This wall carries a projection 8 which may be engaged by a wrench when it is desired to rotate the cap upon the nipple of the hy-- drant. The cap is flared around its open end, as indicated at 9, to provide an annular face of considerable width. This face is formed with an annular recess 10 having an under cut peripheral wall 11. The sides of the wall diverge toward the outer end of the cap and the recess opens upon the interior of the same. The unrecessed portion 12 of the face is about equal in width to the inner wall of the recess 10 and is inclined inwardly. The cap is internally threaded as indicated by the numeral 13 and the threads extend from the recess 10 toward the wall 7.

An annular facing ring preferably formed of brass, is carried upon the inner end of the cap 5 for engagement with the body of the hydrant. The outer edge of the ring is flush with the periphery of the flared portion 9 of the cap and the inner edge is curved or formed concave, as indicated by the numeral 15. The ring is formed with a flange 16 which fits within the recess 10 and which is prevented from rotating therein by means of the lugs 17. The lugs 17 are formed upon the peripheral wall 11 of the recess 10.

In making our improved hydrant cap, the facing ring is placed within the mold and the cap proper cast onto the same. It will be seen that a cap of this construction may be very cheaply manufactured, is not weakened in any manner by the addition of the facing ring and will not corrode fast to the hydrant. Since, as before stated, hydrants are always manufactured with brass nipples, it is unnecessary to have the interior of the cap which threads upon the nipple flange and lug connection between the ring 10 and body.

In testimony whereof We affix our signatures in presence of tWo Witnesses.
